uncover the hottest planet today

The hottest planet ever discovered turned out to have a temperature of 2250 ° C, almost as hot as some stars. The new Planet WASP-12b is a time 1.5 times more massive than Jupiter. 

Interestingly WASP-12b only need 1 day ntuk around its parent star, at a distance of approximately 1 / 40 of Earth-sun distance, or about 3.75 million km. The planet is so close seemed to be in the arms of the star it is so the hottest planet ever found. Other planets are also very hot is HD 149026b, which is much darker than the surface of the charcoal with a temperature 2040 ° C.

WASP-12b was found by Leslie Hebb and colleagues used a giant sky survey called the Super Wide Angle Search for Planets (SuperWASP). Collaboration uses 2 device telescope in the Canary Island, Spain and South Africa. The goal is to find signs of transit of the planet, which is going through a star and make the star's light dimmed a moment when seen from Earth.

Extrasolar planets are too dim compared to the parent star, making it very difficult to measure the infrared light or heat emitted by the planet directly. To solve this problem, various observations made just look at the planet transits its parent star. Thus not only be known there are other objects that orbit a star but can know also the size and orbit of the planet's distance from the transit observations.From there it can then be calculated temperature yangg planet orbiting it.

In general, Jupiter-sized planets formed far from its parent star and then migrate to the area near the star. This happens because near the star there is not enough gas and dust to form a world of giants.Most of the exoplanets in fact have orbiit period of 3 days or more.This mechanism is expected to hold the planet to not migrate closer to the star. So when the planet formed and moves into, there will be something that holds them so that its orbital period is only 3 days.WASP-12b The existence of planets with orbital periods only one day is indeed surprising.

The size of the WASP-12b is also very surprising, because the extent of which Jupiter is 1.8 times larger than the estimate of a giant gas planets to grow.

We have a team of researchers who discovered the WASP-12b did not find the answers and explanations. However, radiation from the parent star, on WASP-12b could be mengembungkan the planet. The composition of the planet is also rich in metals such estimated its parent star, thereby increasing its effect. Planet rich in heavy elements have a lower density than the metal-poor planet.However, further research of the WAP-12b will focus on observations of ultraviolet light to reveal the planet's atmospheric conditions, whether they have been exposed or have had evaporated by the parent star.
